Answer:
The equation of the circle is (x+3)^2 + (y-4)^2 = 16.
Step-by-step explanation:
The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by (x-h)² + (y-k)² = r²
Where (h, k) = center coordinates and r = radius.
36=2x-4 so add 4 to each side to get 40=2x then you divide each side by 2 to get 20=x
So perimeter is adding all sides
In this picture, you have all sides, so add them up!
(2a-3)+(3a+1)+(2a) = P
So this expression shows that we're adding all sides that gives us the P, or perimeter :)
You work 50 -40 = 10 extra hours per week but get paid for 1.5 times that, or 15 extra hours. In all, you're paid for 40 +15 = 55 hours per week.
.. (55 h/wk)*(4 wk/mo)*($16/h) = $3520/mo
Your gross pay for the month (4 weeks) will be $3,520.
20X0.3= 6
30X0.3= 9
40X0.3= 12
